To ctZZ whom it may concern:

Be it known that I, HENRIK VI Lossgacitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inventeda certain new and usefullmprovementin'Machines for Rolling Oar-Wheels, ofgwhich the followingis a' full, clear, and exactdescription;

The primary object ofthis invention is the a suitably-formed blankfof approximately. the shape of the finishedarticle may'while hot or plastic be' reduced to size and shape for final tread formed simultaneouslyorpractically at the same time.

In carrying out tlieinvention thereisfemployed a Work-supporting carriage, movable upon Ways andh'avingfa horizontal spindle, upon which the work is supported vertically, and three sets of independently-controllablerolls are used, one set for drawing out the web, another for forming the treacl;.and another for acting upon the lateraledges of the tread, and these rolls. are mounted upona suitable frame, together with means for controlling them, all as I will proceed now to particularly describe and finally claim.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a partial top plan view and horizontal section taken substantially in the'plane'of line A B, Fig. 2. Fig. 2 is a side elevation, partly in section, of the forward end of the mill. Fig. 3 is a top p'lanview of the parts shown in Fig. 2, partlyin horizontal section. Fig. 5 t is a frontend elevation 'with some of the parts in section. Fig. 5 is a sectional detail, on a larger scale, of one of the edge rolls. Fig. 6 is a top plan view of the edge roll of Fig. 5. Fig. 7 is a horizontal section, on a larger scale,

of tho tread-roll.

production of a rolling mill'by means of which A suitable bed-plate 1 is provided, upon which are erected the stands 2, provided with ways 3, in which is mounted a carriage 4, having a horizontally-arranged spindle 5, upon which the blank 6 is mounted, so as to stand infa vertical plane. This blank is herein shown as acar-wheeh'having approximately the shape which will be given to it by the operation of the apparatus, its hub having been punched in order that it may be mounted 6o uponthe spindle 5 for treatment in the mill. Any suitable provision may be made for moving the carriage for the work into and out of the mill. Oomplemental rolls 7 are provided with a profile corresponding to the face and back of the wheel between its hub and the inner portions of its tread, and these rolls are arranged convergently in rotary ro1l-holders 8, in which they may be secured by gibs or keys 9 or other suitable means. The roll holders 8 are'mounted in bearings 10, which are adapted to turn upon their vertical axes,

. so that the rolls may be moved toward and ,from the work, and the said roll-holders have ,rotary motion imparted to them by means of coupling-rods 11, having a universal -joint connection with the said roll-holders and with shafts 12, mountediin bearings 13 and supplied with beveled gears 14, which in turn mesh with similar gears 15 on a shaft 16, mounted in bearings 17 on. the bed-plate. The shaft 16 ,ispositively driven from the en- ;gine-shaft18,mounted in bearings 19, close to the bed-plate and having a driving-gear 20, meshing'with an idler 21, which meshes with the gear 22 on shaft 16.

In order. to moverthe rolls 7 toward and from the work, each roll-holder has its forward end mounted in a block 23, which is movable in ways 24 on the bed-plate, and each block 23 is connected by a link 25 with a crank-arm 26 on a vertical shaft 27, and these vertical shafts .27 are providedwith arms 28, Figs. 3 and 4,'which are connected by links 29 with a cross-head 30, mounted upon a traveling nut 31, engaged by a screw 32, which in turn is mounted in bearings 33 and has at its end a pinion 34, which meshes with a pinion 35 on a short shaft, the other end of which has a pinion 36, which meshes I00 with a pinion 37 on a shaft carrying the gearwheel 38, which is driven by a pinion 39 on,

the work is arranged a tread-shaping roll 41,

having its hearings in a carriage 42, mounted in ways 43, and the axis of this roll 41 is in substantially the same horizontal plane as the axis of the work. The roll 41 is adjustable toward and from the work byhaving its carriage connected with a screw 44, mounted in bearings 45 and having a nut 46, upon which is arranged a worm-Wheel 47, which is engaged by a vertical shaft 48, and this shaft 48 in turn has a beveled gear 49, whichis engaged by a beveled pinion 50 on a shaft 51, which carries a gear-wheel 52, meshing with a pinion 52 on a shaft of an independent motor 53, so that this roll 41 is controllable in dependently of the pair of rolls 7.

The companion roll to roll 41 is designated 54, and the profiles of the rolls 41 and 54 correspond substantiailywith the flanged tread of the wheel to be produced. The roll 54 is hung in an arm 55, mounted upon a shaft 56, and this shaft has rigidly fixed to it a toothed segment 57, which in turn meshes with a pinion 58 on a shaft 59, which is provided with a gear-wheel 60, which in turn meshes with a gear 61 on a shaft 61, which carries a gearwheel 61", which meshes with a gear-wheel 62 on a shaft 63, which has a gear-wheel 62*, which meshes with a pinion 64 on the shaft of a motor 65, such as an electric motor, so that the roll 54 may be controlled independently of the roll 7 and also controlled independently of its companion roll 4]. in order to insert and remove the work. It may prove preferable in order to secure more perfect roundness of the finished wheel, as well as to help the formation of the wheel-flange, to have another idle companion roll similar to roll 54 and similarly fed and located below the wheel-center, just as roll 54 is located above it.

In order to limit the lateral flow of the metal in the rim and to form and finish the edges of said rim, there are provided the independent edge rolls or idlers 66. These rolls 66, as shown more in detail in Figs. 5 and 6, are mounted upon bushings 67 upon eccentric shafts 68, arranged obliquely in their bearings, and the shafts 68 are provided with worm-wheels 69, which are engaged by right and left hand worms 70 on a horizontal shaft 71, (shown more in detail in Fig. 3,) and this shaft 71 is connected by gears 72 and 73 with a shaft 74, the latter provided with a handwheel 75, bymeans of which the eccentricity of the rolls 66 may be varied and the width of the rim of wheel controlled. The wormshaft 71, admits of the rolls 66 being moved away from the work in order to permit the insertion and removal of the work.

As shown in Figs. 1 and 7, the roll 41 is mounted to turn upon a stationary shaft? 6, arranged in bearings in the carriage 42. Steadying and centering rolls 77 may also be supplied in the carriage 42 for engaging the rim of the roll 41. Also shown in Fig. 7 is a lubricating device for the hub of the roll 41. -Thus it will be seen that the various sets of rolls for rolling the web and for forming the perimeter of the tread and for edging the tread are under ready control,easily adjusted, and all this independently of the main power appliance.

As already indicated,

stantially wrought car-Wheel having for its blank a cast-steel ingot or other form of casting, the wheel with its hub and flanged tread being integral.

I have herein described the use of electric motors for effecting the adjustments of the several rolls, and wish to observe that a platform may be erected adjacent to the handwheel upon which the operator may stand, and within convenient reach may be located the switchboard and other apparatus for controlling the operation of the electric motors, and I have deemed it unnecessary to do more than merely mention these points. Of course the electric motors may be replaced by other independent and easily operated and controlled means.

What I claim is- 1. A machine for rolling car-wheels, comprising a carriage having a horizontal spindle upon which the work is supported in a vertical position, a pair of converging rolls adapted to shape the wheel between its hub and rim,

rolls adapted to shape the flanged tread of the' wheel, and complemental lateral edge rolls, combined with power appliances for driving the converging rolls positively, independent means for moving positively both of said converging rolls into and out of position and for retaining them in position, independent means 1 for moving the tread-rolls into and out of position, and independent means for moving the edge rolls into and out of position.

the machine is especially designed for the production of a sub 2. In a rolling-mill, the combination of latwhich it is mounted, means to adjust said carriage and its roll relatively to the work and controllable independently of the remainder of the machine, a oomplemental suspended tread-shaping roll and means for controlling it independently, web-shaping rolls, means to drive said web-shaping rolls positively, and independent means for moving the said web-shaping rolls into and out of position.

4;. In a rolling-mill, a pair of rolls, rollholders therefor, supports for said holders, bearings for said rolls, rock-shafts, connections between said bearings and said rockshafts, a screw, a traveling nut on said screw, and connections between said traveling nut and said rockshafts, combined with means to rotate the screw and thereby rock the shafts to move the rolls into and out of position.

5. In a rolling-mill, a shaping-roll, a carriage in which it is placed, ways for said carriage, a screw applied to said carriage, a nut applied to said screw, a worm-wheel connected with said nut, a worm-shaft meshing with said worm-wheel, an independent motor, and connections between said worm-shaft and independentmotor for actuating the carriage.

6. In a rolling-mill, edge rolls, an eccentric shaft for each of them, a worm-wheel on each of said shafts, a shaft having right and left hand worms meshing with the said wormwheels, and a train of gearing interposed between a hand-wheel shaft and said wormshaft for adjusting the said rolls relatively to the work. i

In testimony whereof I have hereunto set my hand this 25th day of February,.A. D. 1902.
